Mission: christmas present!
Characters: it's annabeth.
Details: her laptop has lots of dumb designs on it, but also can change size and shape. so she'll be working through her laptop trying to cobble together the design for a shield that can go from small to shield sized, and would try to make it with thatium if she doesn't encounter any roadblocks, inscribed with the Song. the present portion is because she literally just wants to give it to percy, but she might make more shields at a later point if it goes well.
