Dengais truly had no chance of escaping. Rean, Roan, and Kanglia were enough to gain the upper hand against Crowley, and Kentucky wasn't even part of that battle. Now, against Dengais, Kentucky was there. Let alone that Nolui, a Late-Stage Spce-Time Realm just like Dengais, was there too. The Vruves might be strong, but they were not that ridiculous.
Nolui was the one to give the last blow, ending Dengais' life right there and then. It's too bad that someone like Dengais obviously had his own Pocket Dimensional Realm, so anything in his possession was definitely lost with his life as Pocket Dimensional Realms collapsed after their owner's death.
The rest of the cultivators from Rean's group also managed to kill another two Peak Stage Elemental Space Realm Vruves, but another five still escaped. Nonetheless, their side had a major victory. The only loss on their side was a guy called Fenpol, with whom Rean barely had any interaction.
