Reference Notes

  1. Visit Praxis' Notes Section for explanation.
  2. Based on the numbers seen in Episode 1x13 - "Revelations, Part II", Patricia was 13-years-old when she got pregnant with Helen and 14-years-old when she gave birth to her. Helen's father Gregory was age 20 / 21-years-old when Helen was born.
  3. The year of 1907 is conjecture based on Gregory's last known whereabouts mentioned in Episode 4x11 - "The Depths".
  4. Being that the last known whereabouts of Gregory is said to be his trip to Bolivia in 1909, it means that he had disappeared from Helen's life sometime later in 1909 or afterward.
  5. The 1 to 1.5-years worth of regular solar time spent on the surface with the Cabal between 2007 and 2008 is obviously not counted towards this.
  6. Also based off of Ashley's comment in Episode 1x07 - "The Five" about Druitt being "someone from her days back in London before she set up shop here".
  7. Speculation: The show seems to adopt the actors' ages for their characters to a certain extent, in particular their year of birth. Only in the case of Helen Magnus is a similar birth day used rather than the year. Based on Ryan Robbins who plays Henry being born in 1972, and estimating that Young Henry was around age 8-years-old when Helen found him, this potentially places the year as being roughly 1980.
  8. As most high school graduates are 18 / 19-years-old when they enter college as a Freshman, this potentially occurs in the year 1994 / 1995 depending on when Will's birthday is and the school system's cut-off date. In the U.S., children must be age 5-years-old before September 1st to enter Kindergarten.
  9. Please reference the Notes Section of this episode. There are conflicting differences about this location as seen in the Sanctuary universe vs real life.
  10. In Episode 4x12 - "Sanctuary For None, Part I" Capt. Franklin states that Will left the OCPD to work for the Sanctuary Network 4-years ago. Due to the Season 4 finale taking place in January / February 2012, it places the premiere Episode 1x00 - "Sanctuary For All" in that same time frame of year in 2008.
  11. Even though Helen is last stated as being 157-years-old in 1x07, due to knowing that Ashley's birthday occurs roughly two months before Helen's and based on Ashley still being 23-years-old by 1x09, it means that neither of the characters has celebrated their 2008 birthdays yet as of 1x09.
  12. Timeline Dates for Episode 1x12 - "Revelations, Part I" through Episode 2x03 - "Eulogy" placing event occurrence in January / February 2009 is conjecture based on "Revelations" U.S. air dates starting in early-January 2009. All 3 subsequent season finales are placed within this time of year to help keep chronological continuity. Also, being that a season of TV is considered to span the length of a year, this matches up with Sanctuary For All being a year ago in January / February 2008 based on Episode 4x12 - "Sanctuary For None, Part I" being 4-years later from it in early-2012.
  13. Speculation: Based on John's comment of "It seems business is never finished with us despite our losses" and the tone in which it's said, this may mark 1-year since Ashley's abduction / 'death', placing the episode in roughly early-January to mid-February of 2010.
  14. For the cut off scene in the Avatar Chamber near the end of "Kali, Part III", we learn in Episode 3x02 - "Firewall" that Gregory Magnus accesses the Avatar Chamber in Praxis to have Will relay a message to Helen. In Pax Romana we learn that because he broke their most sacred laws in order to do so, it results in him then disappearing at that moment from Praxis to go into hiding as a fugitive from Senate Authorities for the next several untold amount of weeks until Helen arrives to treat Kanaan.
  15. Speculation: Her birthday most likely took place after Episode 3x16 - "Awakening" as Episode 3x17 - "Normandy" occurs in the month of June, just 66-years earlier in 1944 rather than in 2010.
  16. Speculation: Based on Henry building his FOSSS jacket, this episode potentially occurs maybe about a week to a month prior to "Sanctuary For None", placing it roughly in December 2011 or January 2012 if "SFN" happened in January or February of 2012.
