Outstanding. As long as there is at least mild spookiness. Non-spookiness would be in poor taste.

'ernbas' (I believe 'ernmaiss' is a form of this) is a nicely effective word: It's 'bás' (death) combined with 'íarn' (iron) to describe death from combat

My defense in my witchcraft trial would be that I'm merely running a sanctuary for supernatural creatures that need forever homes

I first assumed it was a French graal reference (holy grail conceived of as a dish); but after reading it, my best guess is a real dish that evokes a shield, hence the odd placement of the dish being on the arm. Not pinging any associations w/ saga, which is more abt cauldrons.
