Underworld Ascendant Post-funding Update #40: Lava

The developers at OtherSide Entertainment are apparently unsatisfied with the use of lava in videogames and detailed a more complex design for the substance that they intend to implement in Underworld Ascendant in their latest post-funding update for the title. OtherSide plans to implement two types of lava in Underworld Ascendant, A'a' and Pāhoehoe:

There are two types of lava we will want to play with, basically thick and thin. Thick lava with high viscosity flows slowly and builds up on itself. This type is called A'a', Hawaiian for stony rough lava.

A flow of A'a looks like, well, stony rough lava. It's painfully slow but there is inevitability to it. It's also known to throw out lava balls of up to 20 feet in diameter. Nothing like lava that throws boulders. Already this lava is more interesting than just a barrier obstacle.

Taking it further, what can you the player do to slow this down A'a if it's making its way towards an inhabited area of the Stygian Abyss? Is there magic that can slow it down? A way to divert the flow to a different place? Rumors of some creatures that live in these types of flows that feed on the matter that the lava consumes? They might not be happy about being diverted away from some rich fertile areas of biological goodies.

The second type of lava are fast flowing rivers of death. This is called Pāhoehoe, for smooth unbroken lava. Really makes you want to live on the big island doesn't it? This type can move very quickly; in some eruptions it has been clocked north of 120mph. Try running from that.

This type of lava can burrow directly through rock, or creating new rock overnight, such as lava tubes. What kind of new areas could this unlock for the player? Ancient ruins of civilizations from the before times? An undead graveyard? Chances are whatever it is it was buried for a reason.

We look at the ecology of the Abyss as a living thing. This includes a volcano, with the lava flows forming an almost as a living breathing entity, and one that dynamically changes the landscape of the world.
