The Conclusion of the London Horticultural Show
From Fallen London Wiki
10 August 2023
Players who have not yet begun the summer event should do so before Monday, August 14th, when that will become impossible. The event will fully close on Monday, August 21st, so follow matters to their conclusion before then. Estival tokens will be retained for future events; unspent Prestige and Service will be cleared at that time.
