Im going to cap thing's to see what hint's or clues there are to this. Let's begin:
1) The man speaking. No name, nothing. Not even a face. Unlike the trailer for Kuvakei which we SEE him. This one is bare and blank with just a voice.
'From the formless void, this brings an entity. more primordial than the elements themselves. in it's wake, it will follow a storm."...."In it's wake it will follow a storm.'
2) We have Sarum and her close councilor. About heretics constructing a gate.(This is only a massive hint, as CCP has been wanting to bring expansion to EVE for a long while now. So why not event it. But interesting to make the event as this.)
3) Drekar Alliance command. As stated before, they were robbed for billions and trillions and asset's removed. The fact they were able to rebuild, so much so to this point is pretty amazing. But let's look through what they have as their commanders. 1- Dust CO, 2- Valkyrie Co, 3- Capsuleer CO. A hint most likely all three will need to work together in order to accomplish the needed missions.
They are meeting at a "new" kind of unseen gate. And from the looks, is VERY large. Also, the fact that this will change the eve universe forever. This is a very big hint, that this will change many power houses and players within all Empires. To see who, and what is affected greatly will be shown over time.
3) The Imperial fleet. Within Aridia. This can only come to that the main houses in Aridia will be told to, or given the job of Destroying this gate. This means it is something the Empire will not sit idly by. As from what we see, is a very large fleet indeed.
4) A hint on this new gate. It launches an EMP charge within it's surrounding area. We watch this sequence being done with 1:30 in.
Personal thing: That fleet sequence for Drekar, then the Imperial warp in....beautiful.
a- no cyno on field - titan bridges in? lits immediate DD on a hel? interesting...
5) So, are both fleets officially lost? Where was the titan within the wreckage?
This does seem like there will be a massive coming and new lands to explore. As well as, who is supporting the Drekar alliance? Who really is behind the chess pieces for them?
Hopefully soon, we will find out more, or be given more clues.
