................................ Winter approaches. The Jotunn have made their ice fortresses 300 feet high by now, with their combined efforts. They have made them with permafrost, instead of frozen sea water. The jagged spires of permaforst will withstand dragon's fire, defying the vile lizards that have sought war and found it forthwith.
The bountiful Summer brings endless fish, whales, sharks, turtles, gulls, and all other sea life, feeding the Jotunn horde. Trapped on their island, they have nothing better to do than eat, brawl, and reproduce. Their numbers will quadruple in 30 years. The King encourages brawls to sustain a fighting edge, but forbids killing each other. He insists we will need every Jotunn for this battle. Birthratess of Mumakil has increased as well.
Winter is coming. But summer and autumn have to pass first.
You said Winter was coming... but okay. The Summer heat brings suffering to the Jotunn, as does the dragon attack. This brings immensely increased rage and unrest in the Jotunn, which only strengthens them. Their ice powers begin to grow stronger with rage, though abated by the heat. Come Winter, their power will explode like an ice volcano from having built up by rage.
The Elves have begun to experiment with magical mechanisms.
