I had nothing better to do at home so I made a few stuff I would eventually post in the Slayer's Keep subforum if ever you guys would approve. So here it is:

A map I made. I know it's sucky, but yeah... :nuke:
Navigating Around the Slayer's KeepThe ArchivesA wide structure built entirely out of pure black stone, the Archives houses important records and secret histories written and amasses by the Slayers over the course of time. Apprentices are generally not allowed into the Archives on their own. They need their mentor or another Slayer's permission and company. This is to ensure that the apprentice will not cause 'unwanted' troubles on the precious materials hidden within. The borrowing of materials is allowed, but only inside the Keep premises. If a Slayer has to take materials beyond the mountains, the permission of the Ablest is needed.
Slayer's TempleQuarters for Slayers once they return to the Keep. It is also a place for the Slayers to update each other on world news and events. Some advanced teaching may also take place here. It is quite richly furnished, with two large, ornate baths for men and women.
Nurturing GroundsWhat can be considered as training fields. A wide, open-area temple with the huge roof supported by a total of three hundred pillars surrounding the area, this is where Slayers teach their apprentices to harness and use their magic without causing lasting damage to the nature around them.
Apprentices' QuartersSmaller and less-furnished than the Slayer's Temple, this is where the trainees are housed. Males and females are separated, and are further divided into age groups (5-10, 10-15, 15-25, etc.) The oldest apprentices in their age groups take charge for their group's welfare and assume certain responsibilities.
Ablest's TowerWhere the Ablest resides. It also houses material that are only for the Ablest and the most powerful Slayers' eyes. Here the Ablest trains his/her apprentices (it is somewhat tradition that the Ablest's apprentices are kept from the others, but they undergo far more difficult training). This is also where the Ablest runs the keep and summons his/her Slayers if they are to discuss something very major.
Some Additional Information about SlayersOutfitSlayers have no definite uniform. They all usually wear what they find to suit their own tastes. Though apprentices may eventually adopt the way of clothing of their mentors (example: preference of cloaks, elaborate hairstyles). Everyone is pretty free to wear whatever they want, just don't walk down the streets of the Keep nude or the Ablest would very surely blast your behind with a nasty bat of invisible Air.
Weaponry and Combat skillsAn apprentice would usually learn what his mentor has to teach, though he may choose to learn extra things from another Slayer. Again there is the pattern of similarity between Slayer and apprentice, though apprentices are encouraged to develop and/or find their own ways of combat. This mode of learning is usually not popular.
Deference to RankApprentices know how to defer to their and one another's mentor. A title of 'Master' or 'Mistress' is used when talking to a full-pledged Slayer. Obeisance is also expected. Slayers may order another's apprentice, but not too often. Failure to comply and punishments are up to the Slayer's discretion. The Ablest is addressed as Master by apprentice and other Slayers alike. The Ablest in turn addresses the apprentices and Slayers by their first names or second names, whichever he deems fit.
Overall Way of Life in the KeepThough the Slayers have a sizable fortune that when amassed could buy half of Olencia, life within the Keep is relatively simplistic. Though the Slayers and their apprentices might wear luxurious clothing, their way of life is far from exuberant. Apprentices work to grow the crops and animals the Keep might need for sustenance, usually with the aid of the magic that they are learning to control. Some Slayers may maintain personal gardens. All in all it is a work-for-everyone community; even the Ablest is expected to do his share of the planting and harvesting when he is present.
*For the magical energy used to nurture crops, Slayers and apprentices use the nearby waterfall, located east of the Keep.Average Time of Training from apprentice to SlayerThere is no definite time for an apprentice to become Slayer. It relies heavily on two things: a.) The apprentice's natural talents and b.) the talent and experience of the Slayer mentoring that apprentice. The training's hardest part is usually getting the apprentice to 'sense' the magic around him/her. This part alone may last up to twenty long years. Once it is done, however, only an additional three to five years is needed for supplementary training before an apprentice may be deemed ready to cross into the Dragonlands.
...and I'll add more when I think of them. Hope you like it. XD
