Alright, I absolutely love this design, seriously, Saber's Riders have had some rally great designs and I'm all for it. For the name Durandal, I get it sort of, since popular legends depict Durandal (the sword) as being made from Durandana (Hektor's spear), and since it's a trident, it sort of fits the bill.

For his element, I'm not too sure, some people here are speculating a time or magnet theme, but for me, I'm somewhat leaning towards ice, since that's an element I'm surprised they haven't implemented yet.

So that leaves the guy with the corrupted King Of Arthur (Who might be Mordred?) as our main antagonist, possibly Master Logos, or one of the other Meggido or Desast, whatever he's doing.
