the Wizard's Manufactory

Merl Secret-Fire handles all Guild dealings with the magical arts.  If you would like to learn a magic spell (with a new skill point), Merl grumbles quite a bit before charging 100 SP for 1st level spells, 300 SP for 2nd, and 600 SP for 3rd.  He can sell you each spell as a scroll instead, which saves you from paying the MP cost of the spell and does not require a free skill point, but only those trained in magic (having 1 magic skill point) can use magic scrolls.

Spell implements, like wands and staves, can be purchased from Lucan, the merchant.  Each unlocks one spell of your choice.  Merl will imbue your implement with additional spells at the same prices listed above.

If you can catch Merl in a good mood, this door may lead you to something wonderful.  Otherwise, it remains locked.
