What is a Thunder Stone, and where to find one in Valheim?

A Thunder Stone is a unique resource used to make the Obliterator. Once made, players can use the Obliterator to destroy useless resources or items within seconds, but finding the Thunder Stone you need for the Obliterator is difficult. Unlike most items in Valheim, players can't craft or find a Thunder Stone. Instead, players must purchase the Thunder Stone for 50 Gold coins per stone from an NPC Merchant called Haldor.
