Im on my phone right now but it looks like they are in the act1.zip file attached to the post you quoted. I'll find them in arkenforge later today and repost if not.Sorry to necro an old thread, but I['m planning to run this adventrue for my group and can't seem to find the maps you mentioned in your post (other than the one attached.) Which discord would they be located in or do you have a direct link?
.rwmap &.rwmeta are the file types used by arkenforge but it can export to most other formats, were you looking for a different format?
