A Silver Confidant

This opens up 3 new random dailies per day from 2 new NPCs placed in the Silver Covenant Pavilion: Narasi Snowdawn and Savinia Loresong

Narasi offers two of these:
- A Leg Up
- Rescue at Sea
- Stop The Aggressors
- The Light's Mercy
- You've Really Done It This Time, Kul

Savinia offers one of these:
- Breakfast Of Champions
- Gormok Wants His Snobolds
- What Do You Feed a Yeti, Anyway?

All of these reward 1 Champion's Seal per quest, so 3 extra seals per day once you complete this achievement.

If you Faction Switch, the reputation for SC or SR goes back to 0/3000 Neutral. I'm not sure if the Achievement is reset or not (Faction Switch does weird things... I have 1500 quests completed but in my Achievement log I only have 962 completed) I was about 6000 rep from Exalted when I switched.

That's not technically a Feat of Strength symbol. That's the filler symbol used when an achievement gives not achievement points. Neither this achievement nor the Feats of Strength give any Achievement Points.
