Hey folks,
I'm putting the final touches on the last adventure of a Mythos-themed campaign and want to end it with a chase scene as they try to escape from a rampaging Great Old One (resurrected aspect of Mhar). Any suggestions on some good obstacles? The chase will be taking place on the nightmare plane of Leng, so no teleporting is possible, so the chase is viable that way. I think some blasphemous geometry and whatnot might be fun, but I'm really just looking for some ideas. Thanks in advance!
