Roar!! Great fang of the wyrm king a request for fluff help

[Nosta]

SO I have finally chosen a new character
A geaslt warblade/Bard level 10
I have bought a handful of Dragon graft parts and has a large dragon theme to him
being titled the War Dragon

His weapon is a +2 PSYCHOKINETIC (burst) screaming (burst) great sword named the great roaring wyrm blade . do to the fact that for fluff the screaming sound is that of a dragons roar and the force is the shock wave of its powerful voice

so keeping with my dragon theme what other things could I add through feats or item to keep up the dragon motif

[Rangô]

I'd go for dragonborn template, in fact, you can whip through Race of the Dragons and you'll find a lot of things related to. I mean A LOT.
