My understanding of Squire Vellis' suggestion was that the scroll remain the hands of the Heroes, or Adventurers, but that it is stored in one of the guilds for safe keeping. The Guildmaster and Guildmistress are both members of the Heroes that arrived during the Land Bond. The scroll would be made available for use by any Hero who arranges for it, or perhaps used up when the need arose to combat our enemies. If storing it in the Celestial Guild with Guildmaster Bluwolf is a concern I would like to offer free storage of the scroll, and any Hero community scrolls, at The Five Crowns. The circle that protects our market space isn't as large as the Guild Halls, but is positioned in a way to require substantial effort to destroy.
We already receive substantial aid, and give it in return, from Lord Longshadow. Your idea, Sir Avaran, sounds like it would greatly benefit our efforts and the Guildmasters can discuss requisitions of spellcraftable scrolls from their greater chapter houses if they are able to. However, it is my understanding that a vast majority of resources for the war effort are currently engaged elsewhere. This is old intelligence so please take it with a little salt.
Warmly,
Kevar
