Rather than have all feather tokens look like boring single feathers, I would rather they be pins made of feathers and other materials crafted into decorative symbols. Some purists might have them be single feathers till detect magic is used. It doesn't say there is a command word, so I'm thinking it should be pinned to clothing, then activated by pulling it off, and then using it. All are caster level 12. Cost listed is normal buying price. To make it is half that.
In any case, I am going to start with the core tokens, then start adding designs, Everybody can join in.
1: Anchor: Dropped or thrown down on the deck of a ship, It moors the craft in the water so as to render it immobile for up to a day. It is deactivated by pulling it up. Easy for the one who activated it. Anyone else has to beat a reflex save DC17. When it wears out or is deactivated it disintegrates. 50gp.
Notes: The anchors on naval uniforms are identical but usually non magical. Non magical ones usually cost 2 silver and are made of tiny seagull feathers.
2: Bird: The token creates a small bird that can deliver a written message, tied to its leg, to the recipient. The bird disintegrates after getting the recipients attention, leaving the message right in front of them. They come in every possible color. 300gp.
Notes: Non magical ones are very popular. Bird watchers will try to collect them all and wear their entire collection. They sell for from 5 silver for crude ones to 150gps for true works of art that are ready to enchant.
3: Fan: This forms a huge flapping fan in the users hand. This forms a magical breeze that propels a ship with a sail 25 miles an hour. This wind will not stack with existing winds but can be used to subtract from opposing winds. The fan can be used for up to 8 hours, turned off or on, and will disintegrate when let go of. It is colored in shades of blue. It does not work on land. 200gp.
Notes: There is a rare sand colored fan that only functions on land. It can be used on a prairie schooner that has a sail.
4: Feather fall: Two out stretched wings. When the wearer falls over 5 feet a feather fall (3rd caster level) activates. 50GP
Notes: These are common in floating cities and islands. Conmen will sell powerless ones for a reduced t, but they can be magiced.
5: Swan Boat: A swan. This forms a swan-like boat capable of moving on water at a speed of 60 feet. It can carry 8 horses and gear, 32 medium characters, or any equivalent combination. The boat lasts for 1 day (i.e. 24 hours) 450gp.
6: Tree: An Acorn. This token causes a great oak to spring into being (5 foot diameter trunk, 60 foot height, 40 foot top diameter). It’s roots will shatter floors of any hardness. It will burst through ceilings to a surface with sunlight and rain. 400gp.
