The Dalthus Sector first originated when I created the Castigators, my DIY Space Marines. I created the Howling Stars, a lawless and tempestuous area of space which could house most of the typical Warhammer 40,000 opponents a Space Marine Chapter might need to fight. With the creation of The Higher Call, I created the Dalthus Sector proper, situating it against the Howling Stars. My first INQ28 campaign took place in the Borderworlds, that part of the sector closest to the Howling Stars.
With the INQvitational, we've begun to draw things closer together. The experience of complete strangers playing in my sandpit has been an interesting one. Having to surrender a certain degree of control over to other people has been terrifying at time, but it has helped our figures seem as though they don't exist in isolation.
One of things that has emerged from this collaboration is this, a sector map of Dalthus. This is a smaller version of the whole thing, but it's pretty cool!
As always, click on the picture for largeness!
Doubtlessly I'll post more about Dalthus in the future, but it's cool to see others finding something I've created interesting enough to participate in.
