Here is a variation on 2E Canon Event Milestones: the Incursion Event Milestone!

These are events and repercussions in a parallel timeline as a result of a temporal incursion (or other time travel effects). This often is an improvement or other change that affects your game during an altered timeline or alternate realities your campaign may end up in. You can activate these for use if you are in that alternate timeline.

Incursion Event (IE) Milestones have 3 components similar to Canon Event (CE) Milestones, but also a 4th, which discusses the likely timeframe of that incursion. However, you are free to deviate from it however you like!

• Point of Divergence: when the divergence occurs, and sometimes a suggested end to the alternate timeline.
• Traits active during the IE; usually 3, and they are invoked when relevant
• Complication Range indicates what conditions result in a Complication Range increase
• Reconfigurations are special rules active for that period.

The fun with Incursion Events is that it is totally possible that your crew could end up in this alternate timeline and retain memory of it, through some plot device. This could be anything from temporal shielding, to a quantum fissure, to an Orb experience, to the whims of a Q. They could play through the event as their alternate universe counterparts, if that makes sense. You are also free to rewrite the canonical ending of the incursion event!

INCURSION EVENT MILESTONE: Yesterday’s Enterprise

This Incursion Event Milestone is Yesterday’s Enterprise, based on the events of the episode of the same name on The Next Generation. The Enterprise-C, under the command of Captain Rachel Garrett, passes through a temporal rift in the midst of a pivotal conflict against Romulans at Narendra III in 2344. The Enterprise-C is supposed to have been destroyed defending the Klingon colony on Narendra III, which the Klingon Empire considered an act of honor, which led to a new peace treaty. In the absence of that battle, a decades-long war erupted between the Federation and the Klingon Empire.

The Enterprise-C emerged from the rift in 2366 on Stardate 43625.2, encountering the Enterprise-D of this alternate timeline. This Incursion Event ended when the Enterprise-C was repaired and sent back to its original time, better prepared to save the Klingon colony. It was not without sacrifices and unexpected consequences…see the episode for details.

Point of Divergence: 2344 (the Enterprise-C time travels to 2366); ends in 2366 (Stardate 43625.2) when it returns through the temporal rift.

Traits:

• the Federation in a losing war against the Klingons
• battleships instead of exploration vessels
• billions dead

Complication Range: +1 whenever the Klingons are involved.

Reconfigurations: During this Incursion Event, a starship or station changed by this temporal incursion may re-stat for the duration of the event to emphasize battle instead of exploration. For example:

• Change non-combat Mission Profile to match military, recon, or crisis response roles;
• Replace one Ship Talent (or more at the GM’s discretion) to fit a military, recon, or crisis response role;
• Shake up the Ship Roles and ranks as the players wish and agree upon.

These alterations last until the Incursion Event has run its course and the timeline restored (or changed in other ways).
