Dona Tributaries

The Dona Tributaries are a sector full of mysteries, including ancient Xenos ruins.

Eir
Sector capital, also a confluence of warp currents, most ships that lose their path in the warp in this subsector end up here. One major hive city, otherwise mostly agricutural.

Cooleigh
One of many worlds with extensive Xenos ruins, tenatively identified as Eldar in origin (many Xenos scholars suggest they are merely Eldar inspired).

Gwynth
Mostly Feudal world, notable primarily for their many regiments and one major technological city, also the second most common destination for lost ships. For reasons few know, home to a large contingent of the Adeptus Astra Telepathica.

Cult of Dona
Not your standard Saint cult, this is a persistent heresy that claims Dona was herself half-xenos (claims range from Eldar to some other, lesser known Xenos race). Claims that the Tuata are all her descendants, and thus part Xenos themselves. Decried as heresy by the Ecclesiarchy, Ordos Hereticus and Xenos, and (surprisingly) the Adeptus Mechanicus.
