The lectern can be found just south-east of the lodestone on Anachronia near the stairs. It is used to create the Double Escape codex and Double Surge codex, as well as their tradeable variants. Additionally, it can be searched to obtain 25 codex pages.
Players can change the antispam delay for both double Surge and double Escape by using the "attune movement" option on the lectern once either of the upgrades have been unlocked. The delay can be set to any integer between 1 and 5, inclusive. A value of X makes it dismiss any further activations of the ability for X game ticks after the initial activation, making the ability castable every X+1 ticks. By default, the delay is set at 3, or the duration of the global cooldown.
