Joining the Red Magi

On the main Almerian map, at coordinates 23, -23 there is an exit downward into the Red Magi guildhall. Presumably the Red Magi live underground as it is close to the primal fire of the world's core -- otherwise I have no clue why they live in a cave.

the Red Magi guildhall [n, u]
    You see a wooden-framed white wooden bulletin board (updated 2 weeks ago) and Askeen the
Master Pyromancer.

If you are not a member of a guild, you may receive information on the Red Magi by typing 'help
red magi'.  If you wish to join the Order of the Red Magi, say 'pledge me to the Red Magi'.  To
leave it, say 'I renounce the Order of the Red Magi'.  Red Magi may say the command 'advance'.
Askeen's limbs are named head, chest, right arm, left arm, right hand, left hand, right leg, left
leg, right foot and left foot.  Askeen was created by Fixy; the source code was last updated Wed
Apr 25 21:32:48 2007.  The elf race was created by Lost Souls, who wishes to credit J.R.R.
Tolkien as inspiring this work; the source code was last updated Wed May 16 22:45:34 2007.

At the time of this page writing, 'help red magi' is broken and Askeen's info needs a bit of tweaking, but the important information is there. From testing Askeen speaks Sperethiel and Anglic for understanding joins/advances. I believe he would also understand Enochian and most likely Latin.

You say, "pledge me to the Red Magi" in lyrically-accented Anglic.
Askeen looks you over.

          Changed Flezra's instructor patterns from "teach me" to "instruct me
          in".  Sorry if this screws up your aliases and what not, but got tired
          of spells vs. skills conflicts in her responses to 'Teach me x'.

Guild Help Files

      You are a member of the Red Magi of Lost Souls, a guild of powerful pyromancers dedicated to serving neutrality and all it stands for. The Red Magi use fire as a medium for their magickal art.

      Red Magi have very powerful spells, but they tend to take a bit longer to cast than other guilds, due to the fact that it takes time for that power to build up in the mage.

      Due to the delicate magical field needed for magi to weave their spells, they may only wear non-encumbering armour and overarmour (rings, amulets, robes, and so on). Also, magi may only wield daggers and staves, as it is unbecoming of a mage to wield any other type of weapon.

      Those of the Red Order also receive a red robe worn to indicate their membership. This robe is enchanted to offer greater protection against mundane damage than an ordinary robe, and has some minor wards against fire.

      A mage may know up to eight spells at any given time. These spells can be changed for other spells at the Red Magi Guildhall, for a price. There are many spells to choose from, for a list of spells type 'help spells'.

      Being a Red Mage, you now have several new skills that affect how well your spells will function. Type 'help red magi skills' for more information.

      For detailed information on casting spells, type 'help casting'.

      The Red Magi also have their own channel for communicating with one another. This channel is accessed via the commands 'redmage' or 'guild'.
