d100 Strange Doorways in Auldwood

So commoners often find openings and doors to caves and structures on Exile island, Auldwood and Anglerslund. Often people just cover them up so kids don't find them and mess with them. Sometimes locals know about them and leave them alone due to local legend or past failures from looters. Many assumed tombs of the dead so leave them alone like good people. Sometimes people are diggining up old ruins for building supplies and good stones and find something. There are even towns that thing bringing in adventurers under contract to loot the tomb and 50% of the loot. They would rather a share with money than useless magic weapons. Maybe exited villagers tell adventurers passing by in the pub. Perhaps some kids have opened a hole and gone down and now need help?

Holes in hills - fillers for hexcrawls, local village sidequests or perhaps to plant some huge dungeon as a distraction or for later to visit.
