So this is a bit strange but I wanted to post this because I’ll just forget.
So here’s what I noticed:
Goliath and Behemoth are both brutes based around rock and fire, we all know that. But there’s more.
Now we’re on to the Kraken and the Wraith. How are they related? Well for one they both have tenticle-type appendages. But they also both fly and hover. That’s not all. They both create incredible things that science can not exactly explain. Such as the Wraith’s teleport rifts, and the Kraken’s dark matter! So this leads me to the 5th and 6th monster. After the 5th is revealed, the 6th monster might have some possible similarities between them! So keep your eyes peeled.
