Spellpool

The Spellpool was our crowning achievement. Arcane magic made material, concentrated spell energy so pure you could run your fingers through it. It was also the most powerful scrying device ever wrought, and by using it our seers could look far into the future... further than anyone ever had, and perhaps, further than was wise.

• At the top of the Jade Tower, lies the Spellpool.
• About 8 feet across, 3 feet high, with 18" walls made of solid jade, and inscribed with silver and gold runes.
• The silver lines running up the sides of the Tower culminate here, connecting to the pool and acting as conduits for the ley line energy, which slowly refills the Pool.
