North East Tolkien Society
The North East Tolkien Society, formerly known as the New York Tolkien Society, and also known as Heren Istarion, is/was the largest American Smial of The Tolkien Society. The main force behind Heren Istarion are co-chairs Anthony Burdge and his wife Jessica Burke. It is semi-dormant since 2009 due to hardship encountered by the co-chairs due to the great recession.
The smial is located on Staten Island, New York. They published its own calendars in 2008, 2009 and 2010. The 2011 Heren Istarion calendar was available for pre-order but is unclear whether it was eventually released.
Aside from Heren Istarion New York City has a Meetup.com group: NYC Area Friends of J.R.R. Tolkien & Fantasy, that appears to be active as it meets monthly.
