Today's prompt is 'summoned/banished', which is a bit confusing for me because I drew these as the weapon themselves, and don't usually depict them with 'context' or situation, and summoning or banishing something is a scene/context. Them being summoned or banished is a bit tricky to portrayed as an item that are technically 'idle'?

But then while discussing it, I came up with the idea that the sword is a portal that opens up for an entity to come in, it's summoning a thing.

I'm not sure how well it fits the prompt, but that's my interpretation anyhow.
