And I've already bollixed up one of Dyson's maps before, have four interpretations of Owen's Mine...
Variation 1 - A small abandoned dwarven mine has been re-colonized by new tenants.
Variation 2 - The 'Temple of the Well' was a pilgrim site, with adherents coming from throughout the kingdom to be lowered to the sacred pool at the base of the well, with the hope of receiving a boon. However, the area was overrun by barbarians, who pillaged, desecrated, and moved on. The well is still occupied, and worshiped in its own right by its new occupants.
Variation 3 - An alleged 'holy man' has been preaching along the roadside. However, goods and money have been disappearing, as well. He is suspected to be hiding in the abandoned mine. Another party of adventurers tried to root him out, but has not been seen since.
Variation 4 - Deep within an abandoned mine beneath an old temple is a unique bridge, possibly composed of powerful relics. Beware its guardian, though...
Have fun and comments welcome. Thanks again to Dyson for his ongoing creativity and content.
*Update* - Thanks, Dyson, for the shout-out! I really appreciate it!
And, I realized that I uploaded a draft of Variation 4, not my final version - So here's Variation 4a, with a different, more sinister, guardian,....
