I have a deed (Safe Heaven, ironic I know) on the island just North of the incursion point. I logged in today to find a son of nogump on the island, tried to run away which didn't work very well considering that I am on an island and ended up being killed by a rift warmaster.
Right now I am in Irkalla, with no way to go back since my ships are on the island. I would like to know if this is a bug or an intended feature; in that case I might have to move somewhere else. I thought the island would have been safe given that is outside of the incursion zone.
Update: I made it back to the island, a player was kind enough to come kill the Son of Nogump, but the Warmaster is just too strong. I ended up logging off with my bed since the hulking thing is on the outskirts of the island, I can carefully sneak out to my knarr when I log back I think but I can't really do anything within my deed right now.
I looked around and don't see the warmaster, i guess someone already got to it before me.
I've checked the spawn area and it shouldn't be able to reach your island, so not sure how it's gotten there. Might have been someone's dominated pet that got loose. If you see any more of them - let me know (poking me on discord is usually a good way to get hold of me in real time )
Sorry for the late reply, yes a GM killed it for me. I think that a pet going loose is probably the most likely explanation, I had a couple of drake spirits show up after but nothing more. Perhaps someone is playing pranks on me . I figured out how to handle it anyway, I guess if this happens again I can just dominate the beastie.
