You bet! I'll dig up a tutorial for you - my friend has made similar terrain in the past.
Here's one from my friend which comes close:
http://www.terragenesis.co.uk/infopages/page226.htmlEssentially take pink foam insulation board, cut to desired shape, then cover (in my case) 3x with a 1:1 mix of PVA white glue and DAP gap filling compound, and brush on. Makes it very sturdy and able to withstand a lot of punishment.
You can also see in-progress pics on the "Abyssal Realms" Facebook page, where I show shots of the terrain being built, for these particular pieces.
We hit upon aquarium terrain early on and it has been a big hit. Its super cheap and very visually appealing.
The Dark Mariners are my personal favorite faction. I love the look of them, and they're a strong faction in the game. You can check out my battle report #4 here for them in action (they are also in battle report #1):
