How to unlock the Like Thunder achievement in Chronos: Before the Ashes - Definitive Guide
You find this in the second world.
After reaching the second World Stone here, you have two new paths before you. Enter the building (likely on your left), ignoring the bridge for now. The door you see in front of you after entering is locked, but there is a stairway to the left of it. Go down those stairs and turn right. You will see a shimmer in the wall on the other end of the bridge there. This is an illusionary wall, no need to attack it, just walk through it. It will reveal a dragon statue with a blue gem. Interact with it to obtain the Lightning Stone and this achievement.

This can be found shortly past the second travel stone you come to in the second world of the game. You will head left from it, then down some stairs next to a locked gate, and to the right at the bottom of the stairs across a bridge. At the end of a bridge is what appears to be a dead end, but walk into it and it will disappear, opening into the room with the stone. Grab it to unlock the achievement. Follow this section of the Youtube walkthrough to find it.
