We must rebuild the old defenses if we are to protect the Sourcewells. You should try rebuilding the turrets that guard our bastion to prepare yourself for the trials ahead.
Simply gain Planar Charge from Planar Anomalies, then use Nexus Infusion on Ember Watch Turrets to restore and increase their effectiveness.
Excellent work. Nexus Infusion also allows you to heal and upgrade the Turrets, Lifesprings, and Defense Arches at each Sourcewell on the island.
Only through constant vigilance will we protect the Sourcewells from planar invasions.
