1. I think we should be too late with getting word out.
2. I think our Mentor should feel the coming darkness and sends us away with a holocron. knowing he has lit 2 new candles to light the darkness but he needs to get those candles away from him before he gets snuffed out. And dying in the attack on the comm center is cinematic.
3. The attack on the comm center perhaps puts the base on high alert which results in the shuttle getting shot down. Maybe it crashes near the temple and when our mentor dies we run back to the temple and strip it bare and escape into the jungle. To perhaps run into the shuttle crash.
Cool, works for me. The opening scene could be the two of us arriving at the temple ruins as the two survivors of the crash are extracting themselves from the shuttle wreckage...
