"Kol, please remind me what we're doing here again?"
"Have you forgotten already Vutok? We're here to establish a preserve for the majestic Pandacis Giganticus, by order of the Queen Empress, her Royal Majesty Udil Kibkun, Most Supreme High Necromancer of the Furnace of Pleats, herself!"
"I didn't forgot Kol, I just hoped my ears had betrayed me. Pandas? What elvish insanity is this?"
"Now now Vutok, you know very well that the Gigantic Pandas form one of the most elite divisions of the Pleating army, they're especially effective against elves who expect their "harmony with nature" to protect them. However losses against the humans have been high lately and it is our task to breed new replacements for the Pleating war machine. Such a great honour as having the chance to serve our glorious empire in such a crucial matter comes only once in a lifetime my friend!"
Vutok can be heard muttering under his breath, "No doubt because most dwarves don't survive the first chance"
Tulon suddenly came in view, runnig back towards the wagon from the river.
"Kol! There are giant sponges in the river! And two groups of spongemen!"
Kol, the eternal optimist simply said:
"Excellent! This will scare of many a potential intruder! Onwards for the glory of the Furnace of Pleats and her eternal majesty Udil Kibkun!"
The only raw change I've made is to make sponges amphibious, so you might see the occasional spongeman wander around.
EDIT: 3 layers of aquifier? Really?
