GregLink/StarmetalSigilOfMercury

Background on these artifacts and the notation used, as well as a disclaimer on the contested efficacy of the S&S artifact rules, can be found here: GregLink/SandSArtifacts.

The Starmetal Sigil of Mercury is a Level 5 Artifact created using the S&S creation rules (nearly).

5x - Trade down for three lower level powers.
  4: The power of flight (based on SolarAthletics/GregLink)
  4: The effect of a Gem of Perfect Mobility (a level 5 hearthstone). 

(While that's a level '5' effect, I'm not getting 10m per hour either, so I convinced my ST that said effect is around the level of an essence 4 charm.)

  4x 
    3: +4 Strength
    3: +4 Stamina
    3x 
      2: +4 Soak
      2: Soak Lethal with full Stamina
      2: Starmetal Magical Armor bonus (again, this isn't a canon level for it, but I convinced my ST)

The Starmetal Sigil of Mercury was crafted during the first age by a Twilight Artificer trying to demonstrate that he too could work with starmetal as elegantly as the chosen of Venus. Providing resilience similar to the other 4 example pieces, this particular Sigil attempted to capture the true underpinnings of the chosen of Mercury, granting motion and speed to those who attune to it. Carved out of pure starmetal, and forged in the air of a greater air elemental, the Sigil is only two inches high and less than a sixteenth of an inch thick, bent into the symbol of Mercury herself. When pressed against the skin and 25m are committed, the Sigil bonds to the Exalt, sticking onto their skin almost as a brand or metallic tatoo might. Being marked with the symbol, fate itself is alerted that this Exalt commands superior authority over their motion, allowing the Exalt to move in any direction of their choice (including up), at 3 times their normal movement rate. They can stop at any point, simply hovering, travel backwards, or really any other motion of their choice. In addition, the character's own personal motion is also enhanced, as they gain a second initiative roll every turn. The character may act fully on each initiative action, allowing one initiative to declare a full dodge, while the other might activate a simple charm. While the character may still only activate one charm per turn without a combo, the same simple charm may be activated on each initiative if desired, allowing brutally efficient assaults. This also allows the character to move their normal movement on each initiative action, effectively doubling their maximum combat movement rate. In non-combat situations, this enhanced rate is also available, as the character's base rate of nearly anything is doubled, allowing them to heal faster, work faster, and other such things. While this artifact, at first glance, seems quite powerful, the Artificer who created it (and the other sigils) was never well-received by the Sidereal community at large, as there were those who felt that it was Blasphemy for a non-Sidereal to employ the mark of the Maidens so 'frivolously'. As such, as the first age ended, the Sigils were lost, buried with the Solars who brazenly wore the marks as a show of their irreverence for the maidens.
