Echo shard items and functionality

First The Summoning Mirror, A way to summon your allays to you once they are bound to perhaps an Allay-Bound tome, a curse of binding book with an allay connected to it, in a lectern. Next the Ghostly Goggles; made with Leather and echo shards they would show you deaths in the last 6 minecraft days(2 Hours time). Finally the Echo Pearl; This pearl will trigger no matter where it is when the corresponding player dies it will send them to it and cancel the damage, saving their inventory and them, if they attempt to add more the old one will disappear and reappear in their inventory to them, These will act as ender pearls if they hit the ground. they have a crafting recipe similar to the echo compass but with a pearl in the center.
