Tower - Room 78

Here you find another pair of wizards engaged in sorcery. A robed figure waves his arms about as he suspends a blue orb of energy in the air. The other is harnessing magic from a basin on the table. You clear your throat and greet them. The sorceress by the door maintains her focus, but glances at you and speaks:

Don't interrupt.

After watching for a time, you realize these wizards are practicing their concentration during spellcraft.
