So if we are bent on introducing new sets that have never been used before, we better give it some thought before acting rashly.
A variation on the Alfaerie Animals set has long been in use for Rococo, which is based on Ultima. Since it appears that the Alfaerie Animals set has not been in independent use, I have replaced its Withdrawer image with the ox image used in Rococo. This also brings it more in line with the Galactic set, which was the default set for the original Game Courier preset, as that set uses an ox for the Withdrawer and a Kanagaroo for the Long Leaper. Also, its Pincer Pawn image matches the image used for another Alfaerie set that has long been in use on Game Courier. What I think happened is that David Howe made the Alfaerie Animals set first, and then he later designed other pieces for Ultima and replaced that set with the new set.
Each of the other sets has long been in use or is similar to one that has been. The Alfaerie Chess pieces have long been used for other variants. Judging by Archive.org records, I had created my Abstract pieces for Ultima by early 2004. I have long made them available on Game Courier, and they are now the default for the new Ultima preset. David Howe's Ultima-Alt set was previously used on this page and is still used on the animated diagrams page. And your Alfaerie Queens set is a variation on David's most recent Alfaerie set for Ultima, which has long been available on Game Courier, but it differs because some of the images in that set have not been converted to SVG yet.
