Volcanism on Helca
Volcanism on Helca causes many settlements nearby to its sources to be over-engineered and significantly more enduring than most. Though the most prominent range, the Tolkisson Mountain Range contributes little to volcanism.
Occasionally, minor tremors and earthquakes in the Aragratep Chain that goes through Scar Flow will create freak waves, watery sinkholes, and thermal vents produce nasty gasses mixed with the water from Dwindor.

Black MountainIt is considered part of active Volcanism on Helca, though some magic sends the quakes outside of the Curtain of Night, turning it into a weapon.
