Tiaral

Okay, I'll add some ideas too. To be honest, this time I don't really care about the name and I don't want to bother with it.

Brotherhood (alliance?) of steel/blades
Unwavering
Bound by fate/chosen by fate
Strength in unity/united by strength
Winds of success
Fragments of luck/fortune's smile
Unbreakable resilience
The sweetness of freedom
Alliance of great achievements
Spirit of adventure
Hermes/Cronos
Sign of triumph/triumphators
Honor and courage

From the old ones, I liked these the most:
Griffin's Wing
Steel Hearts
