If so, do we know what time it'll actually happen?

Or will we just get and give the gifts whenever available during that timeframe? If the latter, what's the timeframe?

Also, you say it's in-character. Does that mean the gifts should be IC? For instance, if I'm playing an Acolyte and get matched up with a Scarab.. I probably don't want to give them something they actually want/need from an IC perspective. Is a lump of coal an acceptable gift in that case, or are we trying to ensure they're actual valuable gifts?

Either way, sounds like an awesome event.. thanks for putting it on.
