Share this bastion

This makes a link with the whole bastion tucked inside it — the charter, every floor, the register of chambers, the household, and how things stand right now: defenders on hand, stores, and each facility's own tallies and notes. Nothing is uploaded anywhere; whoever opens the link sees a read-only copy — and can download a Roll20-ready map of it with one click. Your bastion turns, ledgers, and milestones are left out — a shared bastion is a handout, not your logbook.

Connect your campaign's Discord channel

This bastion is your campaign — connect the Discord channel for its table. The channel link is a posting key: it stays on this device and never rides your saves, backups, or shares.

Discord → your channel → Edit → Integrations → Webhooks → Copy Webhook URL
Shown on the post button; blank reads as “your channel”.

Find your character file

Paste your D&D Beyond character page link below. Make sure the character is set to Public on D&D Beyond first, or the file won't load.

Current defenders, stock, and ledger
Order reference for every placed facility

Numbered note markers, listed under each floor plan

Palette

At the table

Optional aids while you run your bastion.

Placing a facility no longer marks it finished — clear "Under construction" by hand
When you place a facility, fill it with its signature furniture — edit or clear it afterwards in Furnish mode
Show build time as years and months instead of a raw day count
Show a reference glyph next to creature and spell names — clicking fetches the stat block from Open5e (open5e.com)
