Hole in the Oak: Old-School Essentials

A hole in an old oak tree leads characters down to a maze of twisting, root-riddled passageways, the chambers of an ancient wizard-complex, and the banks of an underground river where once a reptile cult built their temples.

A classic expedition into the Mythic Underworld for characters of 1st to 2nd level.

60 keyed areas, rumour table, loot summary, dungeon background info, suggestions for expanding the dungeon.
Keyed in a quick-reference, bullet point format.
Unlabelled map included for VTT use.
The Hole in the Oak can be linked with The Incandescent Grottoes to form a large, 3 level dungeon with over 115 keyed encounter areas!
