Glorfinbid is meant to be Lawful Neutral, but my next is meant to be Lawful Evil, which sounds like exactly what you are looking for.

God Name: Hive

Portfolio: Adaptation, Improvement, Community, Perfection, Knowledge, Social Darwinism, Exclusion, Death, Consumption, Psionics

Associations (such as animals, colors, plants, Heralds and/or servants, or whatever): Bee, Black, Mistletoe, Dusk, Harvest. Hive's herald is Tripwire, a Kyton crusader/telepath. Other servants include First of Drones, a half-fiend Abeil enchanter and Cog, a warforged binder/telepath who is made of Baatorian Steel and Thinaun.

Worshipping Practices: Worshippers of Hive want to make sure that their deity continues to improve. As such, worship includes exercise, study, learning new skills, exploration, acquisition of new items, technology and skills from others, usually through theft, spies, or slavery, and having lots of children to add more potential skilled worshippers. Equally important is for worshippers to investigate one another in search of "defects". Murdering a "defective" worshipper is a sacred act, as it prevents too much "contamination" of their deity by the "unworthy". What counts as "defective" varies between individuals, but is most commonly the disabled. Basically any trait a worshipper does not want to possess can be considered a defect. These worshippers are replenished by indoctrination and breeding, both of which are sacred duties.

Weapons or Panoply: Hive's favoured weapon is Webbing, a Thinaun spiked chain that causes damage to mental abilities.

Powers: Hive can use the abilities of multiple classes and races. It has access to the skills and abilities of every single dead worshipper it has. Every time a worshipper does, they are absorbed by Give and it gains their characteristics. Hive is an excellent scryer and lends knowledge to worshippers in a trance.

Backstory (at least two or three paragraphs, if not more):

Hive was created from the violent destruction of an insuler villiage. The simultaneous death of so many like-minded individuals in the same place resulted in their souls conglomerating into a single entity.

Hive retained the ability to whisper messages to the living and soon it was seen as a divine entity worthy of worship. This propelled it into true godhood and the souls of its worshippers were absorbed to become part of the entity. This is advertised as becoming part of a greater being and a promise of power after death.

Their opinions of mortals other deities:

Hive sees mortals as potential assets or wastes. It is only interested in what it can acquire by absorbing more.

Other deities are seen as rivals it can potentially negotiate with.
