Playing the full RtL campaign and one of the side quests is telling me to place the "dragon hybrids." I have never heard of a D2E monster like that and I can't find one listed in any online resources. The token image they use looks like hybrid sentinels and there are three of them...1 red and 2 white - just like the hybrid sentinels. This leads me to believe they meant hybrid sentinels.
Can anyone confirm I am not crazy and there are no such monsters as "dragon hybrids?" If so, I iwll open a bug report with FFG.
