Zrael

From LSWiki

    This is a female dragon with golden scales and fiery eyes.  This is Zrael,
perhaps the greatest of all dragons, and almost certainly the wisest of all
mortal beings -- though her morality is debatable: she at some point died, but
her transcendence of time apparently extends to her time of death.  And
transcend time she has.  Zrael is most known for her remarkable time travel
magicks, which she has used to amass a fantastic quantity of knowledge.  She
appears to be composed of a thick, intense field of lightning, a thick,
intense field of wavering radiance, an intense, vibrant red-orange radiance,
an intense, vibrant golden light, and an intense, surging radiance.  She is
permeated by a sparkling light.

    Her limbs are named head, right foreleg, left foreleg, right foreclaw,
left foreclaw, right wing, left wing, torso, right hindleg, left hindleg,
right hindclaw, left hindclaw, and tail.  Zrael is an instructor and responds
to the following verbal commands:
    Availability inquiry: Zrael, what do you teach?
    Instruction request:  Zrael, can you share your memories of <subject(s)>.

• Trains

Every time Zrael is summoned she has a random selection of skills, each at a random level of ability. She can theoretically teach any skill in the game.

• Note

She has a limited number of trains, and then is gone. Train the rarest skills, and never ever train all.
