Foundry VTT
Link your Foundry
Type the code the Animated Battle Maps module shows in Foundry, then approve it. Foundry can then import the maps your membership includes. You can unlink it any time from the account menu. The module needs Foundry v11 or newer.
Only approve a code that your own Foundry is showing right now. If someone sent you this link or code, don't approve it: their Foundry would get your maps.
