Varðinekvas/Old

So, yep, Old 'Nekvas that is. AKA Western dialect with less substrate.

Features

 * PIE roots left almost unchanged
 * retained most of the endings
 * generally satem changes:
 * most aspirated plosives become their fricative counterparts
 * most palatalized velar plosives become retroflex fricatives, aspirated palatalized velar plosives behave in the same way as their plain counterparts
 * some vowels and /VS/ (vowel-semivowel) sequences become diphthongs
 * most /VSV/ sequences become diphthongs
 * laryngeals become /ɒ/ in most cases; rarely their realization depends on a neighboring vowel.
 * no defined infinitive
 * fronting of vowels after fricatives developed from (unaspirated) palatalized plosives

Grammar
The grammar of 'nekvas is mainly fusional and marginally synthetic. (blah blah blah, TBD)

Pronouns
As you can see, the singular and plural pronouns are derived from Proto-Indo-European, like most of the language's lexicon, and the dual pronouns are formed by attaching the suffix -dve (reduced form of duve - two) to either the pronoun root (in 3rd person) or an inflected form of a plural pronoun.

The declension of pronouns is quite regular, although different from the noun declension. Usually it involves declining an "inflected root" by attaching similar suffixes for each pronoun.

The pronouns have two oddities, both grammatical: there is a dual number and a distinct locative, both absent in nouns and verbs.
