A Scorch Mark
From A KoL Wiki
The Scorch appears in The Nearby Plains south of The Misspelled Cemetary after Fernswarthy's grave is found during the Wizard of Ego quest if a player is at Level 6 or higher. Level 4 or 5 players will see A Temporal Rift leading to The Nearby Plains in the Distant Past or a A Small, Bright Light whether or not that player has ascended.
Clicking on it gives the following message:
There's a small burned patch of ground here, smelling of used-up magical energy. You know that feeling you get from chewing on tinfoil? That's what it smells like.
