Liam didn't use any of his martial arts or spells.
Anything that had even the tiniest detail of his fighting style had to be avoided.
His plan was simple, but shrewd.
Using the feud between Erivol and Ucladd, he'd kill both 'himself' and two nobles from each city.
Of course, he'd use his dear inscription master's methods of killing to achieve his goals.
No one knew Revel died but Liam himself, but the real Blood Demon's fate was unknown to the masses.
With the odachi and vampiric nails, Liam could create a crime scene with Revel's M.O.
The reasons for the attack could vary, but perhaps the Blood Demon saw an opportunity to strike when everyone wasn't expecting it.
Or maybe his hatred had flared seeing someone else stealing his name.
It could even be jealousy from Liam's element, which is why he had his core pulled out.
…Who could tell?
