Kakariko

After a chat with the light spirit, you’ll find yourself standing in the Faron Woods. You can go back to the village if you like, but there’s nothing new to be found there. Instead, head northwest past the hippy lantern-seller and into Hyrule Field. You can only exit this area to the west, but before you do, follow the road to the center of the map. You should encounter a pair of goblins just before a bridge that leads north. Before crossing the bridge, look up into the tree nearby; a Piece of Heart is located up there. You can nab it with your boomerang. Also, if you check your map, you should see two hills that glow green on it. If you drop down into the area between them, you’ll be able to find a male bug on one of the trees. Pick it up to add it to your collection. Collecting this bug will let you get a larger Wallet later on in the game.

Head west towards the exit; you’ll nab a piece of mail from the creepy mailman before you manage to reach it. He’ll periodically visit you with letters from this point forward, so be on the lookout for him!

Eldin

When you leave Hyrule Field, you’ll be turned into a wolf. You’ll find Telo’s sword down the path a bit; sniff it to learn the scent of the village children, then use Senses mode to highlight the scent on your screen.

You’ll have to destroy three more shadow creatures (using your B-button power) before you can cross the bridge here - only thing is, there’s no bridge to cross! The shadow creatures have sent it through one of their portals to trip you up, so let Midna warp you to the N. Faron Woods portal. The bridge is leaning up against a rock wall right near where you wind up, so walk over to it, speak to Midna, and have her warp it back to Eldin so that you can cross over it. Follow the scent to a gate to the west, then dig under it with Senses to reach Kakariko Village.

Kakariko Village

Damn shadow creatures!

It can be difficult to get the three shadow beings here into your B-button circle all at once; one of them will keep its distance from the other two. In instances like these, it helps to simply lock onto one, attack it until it dies, then use your B-button shadow circle to kill the other two at the same time. You’ll still wind up killing all three.

When the shadow beings are dead, speak to Eldin, another spirit of light, in the lake nearby to receive its Vessel of Light. You know the drill: you need to track down all of the insects that have attached themselves to the tears of light that were shed by the spirit because it got so emo, or something. Time to track them down; most of the insects are actually inside the houses in the village. All are marked on your map, so get to work.

Begin with the house in the southwestern corner of the village, where the southernmost insects are located. If you circle around the building, Midna will show you a path you can take to leap up to the building’s roof. Drop down through the hole up there and activate your senses to reveal that the village children are here, in the "real world" version of the town. When the cutscene’s done, grab the stick from the ground, run up to the flame to set it alight, then jump past the candles on the upper level of the room to light them. Doing so will net you access to the cellar, where you’ll find the first three insects for your collection. When you reach the exit from the cellar, you’ll find yourself in the town’s graveyard, where the fourth insect is underground. Light it up with your Senses and dig it up, then attack it to add it to the Vessel.

More Insects

Return to Kakariko Village and start tracking down the rest of the tears. If you go from south to north, here’s how to obtain them. Many of the buildings will have signs outside of them, if you’re having trouble identifying them.

General Store: Walk through the gate on the ground floor here and find the small hole in the bottom of this building. Find the insect, kill it, and exit through the same hole.

Elde Inn: Walk up the ramp to the south of the general store and jump across to the hotel’s balcony. Drop down to the floor below you, grab a stick from the fireplace, light it by jumping from the table across to the torch nearby, then Place it back in the fireplace to roust the insect in the chimney. Another insect can be found by entering the hotel’s main lobby and taking the stairs up to the guest room above.

Residential House: On the western side of the street, a house contains another insect. Travel two houses to the south and find a small ramp you can hop onto, then jump from roof to roof until you reach the roof of the house with the insect inside. Drop through the weak part of the roof, then push the wooden crate towards the wall to reveal the insect. Midna will let you jump outside when you’ve killed it.

You’ll need to find some nooks and crannies to get into the houses here in town.

Barnes Bomb Shop: Head to the building just north of this large structure and climb up to the roof. You should be opposite a window on the Bomb Shop building; dash into it and you’ll smash through and wind up inside. Head upstairs and ram into the bookshelf that the insect is hiding to release it, then climb up the shelving to reach the building’s exit.

The Northwestern Hills: When you climb out the window leading to the top of the bomb shop, take a left and you’ll come out to the hills above town. To the northeast there’s a building with a diggable entrance where one insect is to be found. To the west, there’s a building marked "Danger!" It seems like the wisest option here is to grab a stick from the ground, set it alight at the torch nearby, then attempt to light the fire in the fireplace. Doing so, though, will blow up the entire building. Quickly exit before this happens, then grab the tears from the wreckage.

Death Mountain: If you head north to the edge of town, you’ll come to a tunnel leading towards Death Mountain. It’s probably a bad idea to head up there, right? It’s got to be called Death Mountain for a reason, right? Well, you don’t have a choice. Head on up towards the mountain, using Midna to hop the first set of obstacles, and you’ll find a series of geysers. The first of the three insects in the area is underground here, so dig it up and kill it.

Head north until you reach Death Mountain proper. There will be four shadow beings waiting for you, one of which will hide in a small box of force shields while the other three attack you. You have to find the entrance to the small box, kill the solo shadow being there, then move out to the other three and kill them all with the B-button circle of death. The penultimate insect is located nearby, so activate your Senses and track it down before using Midna to hop up to the upper level of this area. Move around to the Goron that’s standing near a fumarole, then drop down to the watery area below to find the last insect.
