Installation Guide: Requires One Large Room  

Upgrades Available

Forbidden Section. While handling these books within your library you gain proficiency in Deep Speech. You gain the benefits of the Darkvision spell, but for 12 hours after consulting these tomes. The golden cage around the Forbidden Section protects it from Divinations of 5th level and below. It is locked with a DC 22 quality lock.   ----------------------------------------

This room is suitable for all manner of research purpose. With tables meant for spreading books out on out, space for maps and diagrams, as well as space for up to 300 books on the ample shelves this is a bookworms dream. Installation costs also include your first fifty books. These are all common books without rare or spectacular knowledge. But they form a basis of reference for you on any topic.

Arcana, Religion, History, and Nature checks may be made at advantage while in your library. Additionally, whenever you roll a natural 20 you discover a new book to add to your collection on the relevant topic.

Forbidden Section

These tomes of dark knowledge were exhumed from beneath the sea's surface. They continue to smell of brine and depth. Around them, a high quality cage, meant as much to contain them as to keep others out. The cage is gold and creates a magical barrier that prevents divinations of 5th level or lower from passing through it. And, all spells of 3rd level or lower from functioning at all. A fine gold lock, with only two copies of the key bars the books from removal from their shelves.

By referencing these tomes your eyes turn to pools of black, and you gain sight into the darkness. You speak only in Deep Speech while you are physically handling the books, but can remember and understand what you read and said after setting down the tome. Your darkvision persists for 12 hours.

During any full moon (let's just say the first week of the month) you may perform a ritual from these putrid tomes and conjure an emissary. A small shadow pet follows you and is friendly towards you. They have only 1 hit point, but much like an unseen servant can only be harmed by environmental and area damage. Their form depends on the dark source referenced in your forbidden tomes, selected at the time of installation. It can be changed at the cost of a Limited Downtime and 2 Clout.
